GEORGE E. FOBSYTH, OF CHICAGO, ILLINOIS.

METAL SASH.

Specification of Letters latent.

To all whom it may concern:

Be it known that I, GEORGE H. FORSYTH, a citizen of the Fnited States, residin at Chicago, in the county of Cook nd tate of Illinois, have invented certain new and useful Improvements in Metal Sash, of which the following is a specification.

This invention has to do with metal sash, and concerns itself chiefly with-that type wherein the stiles are transversely lyieldable, thereby producing a snugl tting sash that will exclude the dust an prevent rattle of the sash without binding the latter, under various conditions of weather.

In my invention, I show amon otherimprovements novel means for ad usting the sash to varying widths of window casing and for holding the lass securely within the sash and preferab y under spring tension. I also show an eflicient sash balance whereby the sash may be easily raised to any desired position.

(ertain matter which has been disclosed but not claimed in this application is claimed in my co-pending applications filed December 12. 1910 and given Serial No. 596,924,

and Serial No. 596,925.

Referring to the drawings, Figure 1 is a front elevational view of the sash; Figs. 2 and 3 are fragmentary views showing two possible ways of forming the joints of the sash members; Figs. 1, 4f, 5, 6, 7, 8, 9, 10, 11, 1'2, 13, 1T, 15 and 15 show various constructions for holding the glass within the sash,

' and for adjusting the latter to varying widths of window opening; Fig. 16 is an end view showing a lipping over of the'bevclrd end of one of the glass-engaging strips.

1 designates the sash as a whole, and 2 the window casing: 3 and 4 the cross members of the sash and 5 the vertical members or stiles.

6 is the glass, and 7 the glass-engaging strips retaining the glass within the sash.

In Fig. 2, 8 is a reinforcing shell, whose sides are respectively riveted to the walls of the cross members 3 and 4 and stiles 5 of the sash. In Fig. 3 the reinforcing shell 8 is riveted to the rear wall of the stiles 5 and to the side walls of the cross members 3 and 4. \Vith the latter construction, I have shown the ends of the stiles as lipped over at '5, leaving, however, an open space 9,

which permits he sash to have transverse yieldin movement at this point.

In ig. 4 the glass-engaging strip 7 is formed at its base with an incline 10 to engage a corresponding inclinell of the sash member. The screw 12 when passed through the registering holes of the respective'inclines and screwed into the strip 13, tends to draw the strip 7 into close engagement with the member 5. In this construction and various others which I have shown, the glass-engaging strips gri and hold the glass under spring tension, an are of such a construction that, together with the glass, they can be inserted frontwise into the sash open- In Fig. 6 the glass-engaging strip 7 is formed with an interlocklng lip 14, which engages .a cooperating lip 15, which is fastened to the back wall of the sash member 5.

The interlocking lips 14 and 15 are inclined toward their outer margins thereby engaging each other under tension; after which the screw 16 and its nut 17 combine to securcly hold them together.

In Fig. 7 the glass-en aging stri is pro:

vided with a bevel 18, w ich is hel against the corresponding bevel 19 of the sash memher 5 by the screw 20.

In Fig. .8 the glass-engaging strip 7 is held in position against the sash member 5 by means of the key 21, shown most clearly in Fig. 9. The heads 22 pass through elongated slots 23 -in the transverse wall 23 of the sash member and registering openings 24 in the base 24 of the strlp 7. After the heads 22 have been inserted through the slots above mentioned, the key 21 is thrust forward Patented Jan. 10, 1911.

Application fll'ed February 6, 1905. Serial No. 244,406.

causing the heads 22 to engage the base 24 and retain the strip 7 in position. The inner stri engaging edges 22 of the keyheads 22, as shown in Fig. 9 are slightly inclined, thus holding the strip 7 against the sash member under constant tension. After the key 21 has been thrust forward until the holes .25 register with the holes 25 in the side of the sash member, the screw 26 is inserted and screwed into the block 27.

In Fi 12, the glass-engaging strip 7 is provide at its base with the rentr'ant inclined guide-way 27. The sash member is also provided with a corresponding guide.- way 28. After the glass and its engaging strip 7 have been inserted within the sash opening, the locking stri 29 is also inserted endwise within the gui e-ways 27 and 28 preferably under tension, thereby securely holding the glass-engaging strip 7 and the sash member together.

' In Fig. 13 I employ a secondary strip 30,

directly en aging the glass; which strip can be snappe, -1nto positlon and holding enthe strip 7,.instead of directly resting against the key-heads 22.

In Fig. 4, the transversely yielding adjusting strip 34 is formed along its outer edges with-the ribs 35 adapted to engage corresponding depressions 35 in the window casing guide. The strip 34 when not engaging the groove 2 in the window casing ares outwardly, as shown in Fig. 4 The end portions 36' also incline outwardly. When the strip 34 is, therefore, introduced within the groove 2, it not only engages the v recesses 35 and the bottomof the groove 2 under tension, but also tends to bear against and hold the outer margins of the. sash members at 5 in spring engagement with the sides of the grooves 2*. As the sides of the sash member 5 also flare outwardly, before engaging the groove, there will be a double tendency to exclude dust and prevent rattling of the window sash. The side of the sash member is provided ,with a slot 39 through which a screw 40, shouldered at 40, is passed into a block 41, thus permitting the strip 34 to have sidewise slidable movement relatively to the sash member 5, whereby to accommodate the sash to varying distances between the bottoms of the oppositely disposed casing grooves 2. The washer 42 underneath the head of the screw 40 is supposed to slightly overlap the slot 39, concealing the latter .from view. After the sash has been inserted within the win-' dow casing and the stop or strip 37 has been placed in position and held there by the screw 38, the sash cannot be displaced from they window casing, the slot 39 being of limited length, whereby the outer margins 5" of the side walls of the sash member 5 cannot be withdrawn from engagement with the sides of the casing groove by. sidewise displacement of the sash relative thereto.

7 In Fig. the side walls of the sash member 5 do t enter within the groove in which the st 'p 34 operates. The block 43, which is ri eted to the interior of the side wall of the strip 34, is provided with a plurality of threaded holes 44, into one of which the screw 44, which is provided with a washer 45, is screwed. The strip may thus readily be adjusted to varying distances between the bottoms of the window casing grooves. By withdrawing the screw 44, the adjusting strip 34 may be retracted and withdrawn from engagement with the window casing groove, permitting the sash to be readily removed frontwise of the window casing. By this construction the guide of the casing may be integral therewith instead of being detachable as a whole or in part therefrom.

In Fig. 6 the strip 34 is formed along its outer edges with inwardly turned lipped portions 34 which engage correspondingly.

lipped portions of the detachable strip 46, the

latter being screwed to the window casing.

In Fig. 7 I show the groove engaging side walls of the sash member 5 bent backwardly and inwardly atv an incline. The adjusting strip 48 is alsoprovided with corresponding inclines, whereby the elongated bow spring 49 not only adapts the sash to varying distances between the bottoms of the casing grooves, but also has the effect of forcing the adjacent ortions of the side walls of the sash IIIQIIHWIS into spring engagement with the sides of the, grooves. In Fig. 8 I

also provide an elongated bow spring 49 also carried by the sash by means of a slot in the inwardly bent tongues 49.

In Fig. 10, the adjusting strip 34is rovided with outwardly flaring lips 52 *ig. 11) which engage under tension the recessed portions 52 at the bottom of thecasing grooves. The adjusting strip 34 is provided with a slot 53, which permits the strip 34 to have sidewise movement relatively to th sash.

In Fig. 12 I provide the outer margins of the sash members 5 with ofiset portions 54 in which .are located the bow springs 55, having ears55 entering coiiperating slots in the said oiiset portions. The outer edges of the sash members 5 are inwardly lipped at 56.

In Fig. .13, the adjusting strip 34 has its edges turned backward at 34 and is automatically thrust forward into yielding engagement with the bottom of the casing roove guides by the bow spring 57 which 1s fastened to the back wall of the sash member 5.

In Fig. 15 I show a side elevational view of a bow spring 49 attached to the sash by a hooked end 49".

Fig. 15 shows a modification of the bow spring feature introducing an anti-friction feature designed to lessen the friction of the sash in the guide. In said figure 49 desig hates the bow-spring which, in this case is secured as by rivets 49 to the transverse member of the stile and carries at its ends antisfriction rollers 49 hearing against the bottom of the guide groove. While I have described the rollers as carried by the howspring 4t)", it is evident that they might applied to any of the other members herein described as operating between the edges of the stile and the'casing guides, such, for instance, as the bow-springs 55 or adjusting versely yieldable engagement with saidguide, and means carried by the sash and capable of movement relatively thereto whereby the sash is held in yieldable engagement with the window casing.
